我正在将大量 .h 和 .lib 文件从本机 C++ 移植到托管 C++ 以最终用作 C# 中的引用 .dll。
拜托,我知道将整个东西移植到 .NET 会容易得多,但如果可以的话,我会的。这是第 3 方,我只有 .lib(无导出)和 .h 文件可以使用。
一切都很顺利,直到我遇到了虚拟功能,现在我遇到了一些委托问题。
我遇到的错误包括:
错误 C3756:“ThreadFunc”:委托定义与现有符号冲突
错误 C2079:“MyWrapTest::MyThreadWrap::m_threadAttr”使用未定义的类“MyWrapTest::MyThreadAttrWrap” ' : 无法将参数 1 从 'MyWrapTest::MyThreadAttrWrap' 转换为 'MyThread *'
为了清楚起见,我将包括本机代码和我现在正在处理的东西。一、原生代码:
#ifndef MYTHREAD_HPP
#define MYTHREAD_HPP
#ifdef WIN32
#include <winsock2.h>
#include <windows.h>
#define STDCALL unsigned __stdcall
typedef unsigned (__stdcall *ThreadFunc)(void*);
#else
#define STDCALL void*
typedef void* (*ThreadFunc)(void*);
typedef unsigned int HANDLE ;
#endif
#include "generaltypes.hpp"
class MyThreadAttr;
class MyThread
{
public:
MyThread(void);
MyThread(MyThreadAttr * tta);
virtual ~MyThread() {};
virtual HANDLE start(ThreadFunc,void *, unsigned *);
virtual int stop();
static void wait(HANDLE);
#ifdef WIN32
static void wait(HANDLE, int);// msec timeout required since 'cancelThread' is no-op
#endif
static void sleep(unsigned int);
static int32 cancelThread(HANDLE hThread); // no-op on Windows (returns -1)!
#ifndef WIN32
static void setCancelStates(void);
static void endProcess();
#endif
protected:
MyThreadAttr * m_threadAttr;
void setThreadAttr(MyThreadAttr * tta);
};
#endif
以及我正在开发的新东西:
